Borealis Visico™/Ambicat™ LE4421/LE4476 Polyethylene Compound, Crosslinkable
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Visico™ LE4421 / Ambicat™ LE4476 is a silane crosslinkable natural compound designed for low voltage power cables up to 6kV. The base material Visico™ LE4421 in combination with the catalyst masterbatch Ambicat™ LE4476 will accelerate the moisture-induced crosslinking reaction. The system is highly active and crosslinks quickly at ambient conditions, in sauna or in hot water. When properly mixed, addition of 5 parts of Ambicat™ LE4476 to 95 parts of Visico™ LE4421 , insulation with excellent thermo-oxidative stability, also in contact with copper as well as aluminum, is achieved. If the insulation is designed to meet the thermo-oxidative ageing demand requiring by IEC 60502 at 150°C in contact with copper, addition of 9 parts Ambicat™ LE4476 to Visico™ LE4421 is recommended. Applications: insulation of low voltage cables for the range up to 6 kV. Additives: Visico™ LE4421 / Ambicat™ LE4476 contains antioxidant, metal deactivator and a drying agent. Visico™ LE4421 contains a permanent scorch retardant additive, ensuring safe processing and enabling the use of a highly active crosslinking catalyst. Specifications: Visico™ LE4421 / Ambicat™ LE4476 in combination meets these applicable requirements when processed using sound extrusion and testing procedure: ASTM D 1248 Type I, Class A, Category 4; HD 603 S1; HD 604 S1; IEC 60502-1; NEMA WC 70; and NEMA WC 71.
